Keeping Farm Animals as Pets in New Mexico: What You Need to Know Before You Start

New Mexico has a deep agricultural heritage, and the state’s wide-open landscapes make it one of the more welcoming places in the American Southwest for people who want to keep farm animals as pets. Chickens in the backyard, a pair of goats on a small rural lot, or a miniature donkey on a few acres — all of these are realistic possibilities here. But the legal picture is more layered than it might seem at first glance.

Before you bring home a pig, a sheep, or even a small flock of hens, you need to understand how New Mexico classifies these animals, which state agencies oversee them, and — critically — what your county or city allows on your specific property. Getting the sequence right saves you from costly fines, forced rehoming, or neighbor disputes that could have been avoided entirely.

Pro Tip: Always verify your property’s zoning designation before acquiring any farm animal. Your county assessor’s website or planning and zoning office can confirm your zone in minutes — and that single step determines almost everything else covered in this article.

Which Farm Animals Can You Keep as Pets in New Mexico

New Mexico law draws a sharp line between companion animals and livestock, and that distinction shapes every rule that follows. “Animals” or “livestock” under the New Mexico Livestock Code means all domestic or domesticated animals used or raised on a farm or ranch, and includes equines, cattle, sheep, goats, swine, bison, poultry, ostriches, emus, rheas, camelids, and farmed cervidae. If the animal you want falls into that list, it is legally livestock — not a pet — regardless of how you personally keep it.

Animals like goats are classified as livestock under New Mexico state law, which means their ownership falls under the jurisdiction of the New Mexico Livestock Board (NMLB) rather than standard pet ownership regulations. This classification has significant practical implications: these animals are subject to brand inspection requirements, movement permits, and health documentation rules that do not apply to companion animals like dogs or cats.

In practical terms, the farm animals most commonly kept as pets in New Mexico include chickens and other poultry, goats (both dairy and miniature breeds), pigs (including potbelly and other small breeds), sheep, donkeys, and horses. Emus and llamas appear occasionally on hobby farms as well. Dogs, cats, and domesticated fowl and birds are classified as personal property under NMSA 1978 § 77-1-1, which gives them a different legal standing than larger livestock species. If you are considering a broader range of farm animals before narrowing your choice, understanding this classification gap is the first step.

Some animals that might seem farm-adjacent are regulated differently. No person may import into New Mexico, capture with intent to keep as a pet, or buy, sell, trade, or possess any skunk except in connection with a recognized zoological park, research institution, or by permit from the department, due to the presence of rabies in skunks. Always check with the New Mexico Department of Game and Fish for any species that straddles the line between wildlife and domesticated animal.

Zoning and Property Requirements in New Mexico

Zoning is the first and most important legal filter for anyone wanting to keep farm animals as pets in New Mexico. Because the state delegates land use authority to counties and municipalities, the rules vary widely depending on whether your property sits within city limits, in an unincorporated rural area, or in a planned community with its own deed restrictions.

In rural, agriculturally zoned areas — classified as A-1 or A-2 in most New Mexico county codes — livestock keeping is generally permitted without special authorization beyond basic livestock ownership requirements. These zones typically cover properties of five acres or more and are designed to accommodate traditional farming and ranching activities. If your property sits in one of these zones, you have the most flexibility of any classification in the state.

Residential zones are a different matter. Residential zones in New Mexico generally permit keeping a limited number of pets as a matter of right, but operating even an informal livestock setup can trigger a land-use change that requires a conditional use permit or a rezoning application. In many municipalities, large livestock like horses, cattle, and pigs are simply prohibited in standard residential zones regardless of lot size.

Planned communities and HOAs add yet another layer. Before applying for any permits, review your HOA’s CC&Rs carefully — or have an attorney review them for you. Look specifically for language about commercial activity, pet limits, noise, and nuisance provisions. An HOA prohibition can block you even when the underlying municipal zoning would otherwise allow your animals.

Pro Tip: New Mexico’s “North Valley” and “South Valley” areas near Albuquerque fall under Bernalillo County’s more permissive agricultural rules rather than the City of Albuquerque’s stricter municipal code — a distinction that surprises many new residents in those areas.

Lot Size and Number Limits for Farm Animals in New Mexico

There is no single statewide lot-size formula for farm animals in New Mexico. Limits are set at the county and municipal level, and they vary considerably. That said, some clear patterns emerge across the state’s jurisdictions.

For poultry, urban areas tend to be the most restrictive. All specific flock sizes, rooster rules, permits, and coop setbacks are determined by individual cities and towns. Urban areas often cap hens at 4 to 15 with permits and strictly ban roosters; rural zones are significantly more permissive. As a concrete example, Albuquerque allows up to 15 poultry units in city limits and even permits one rooster; Santa Fe allows up to 4 hens in city limits with an annual permit; Las Cruces uses a density-based system of 1 bird per 2,000 square feet; and Truth or Consequences allows up to 6 hens with a specific coop permit.

Gallup’s ordinance illustrates how restrictive some cities can be with larger livestock. It is unlawful to keep, harbor, or maintain within the Gallup city limits any horses, mules, burros, cows, pigs, goats, sheep, swine, and all other domesticated animals used in the production of food or other products, except as provided in Rural Residential (RR) Zoning Districts. This type of blanket prohibition in standard residential zones is common across New Mexico’s incorporated cities.

For larger animals like horses and cattle, the typical threshold in agricultural zones is one animal unit per one to five acres, depending on the county. Bernalillo County’s Sustainable Land Development Code uses an “Animal Unit” density system — with no specific numerical cap provided the animal unit density is met, at 1 bird per 2,000 square feet of open area for poultry, with proportional standards for larger animals. Always request the specific animal unit table from your county planning office, as these figures are updated periodically. If you are just getting started, a guide to backyard poultry can help you think through space requirements before you commit.

Permit and Registration Requirements in New Mexico

New Mexico does not issue a single statewide permit for keeping farm animals as pets. Instead, requirements come from two directions: state-level livestock registration through the NMLB, and local-level permits through your city or county.

At the state level, the NMLB oversees livestock ownership under the New Mexico Livestock Code, NMSA 1978, Chapter 77. That framework governs everything from ownership transfers to disease control. Brand registration is one of the NMLB’s core tools. While small hobby herds may not be required to carry a brand, registering a brand or earmark with the NMLB creates a documented ownership record that is invaluable if animals are lost, stolen, or mixed with a neighbor’s herd. The NMLB maintains a brand registry and conducts brand inspections at points of sale and during livestock movement.

Federal scrapie identification rules also apply to sheep and goats. Even if you keep only two or three goats as pets or for personal milk production, federal scrapie identification requirements still apply if you ever sell or transfer an animal. Getting your animals tagged early — even before you plan to sell — avoids last-minute compliance issues.

At the local level, permit requirements mirror the pattern seen across New Mexico for other animal-related licenses. Since New Mexico does not have a statewide program, owners must apply through their local city or county government. The application process varies by jurisdiction but typically involves contacting your local animal control office, city clerk, or county administration office. For chickens specifically, in cities like Santa Fe and Truth or Consequences, a specific “Chicken Permit” or annual coop fee is required regardless of the structure’s size. You may also want to review beekeeping laws in New Mexico if you plan to add pollinators alongside your farm animals, as the permit structure follows a similar local-first model.

Key Insight: Movement permits from the NMLB are required any time you transport livestock across a livestock inspection district line in New Mexico — even for a single pet goat being moved to a new address. Plan ahead if you are relocating, and contact the NMLB before transport day.

Housing, Setback, and Sanitation Rules in New Mexico

Even where farm animals are permitted, New Mexico municipalities and counties impose specific rules about how and where you house them. These rules exist to protect neighbors, prevent nuisance complaints, and maintain public health standards.

Setback requirements — the minimum distance between an animal enclosure and a property line or neighboring dwelling — are among the most consistently enforced rules. A common setback in Bernalillo County is 25 feet from property lines for any coop or enclosure. In many New Mexico cities, a small coop under 120 square feet is considered an “exempt accessory structure” and does not require a formal building permit. However, you often still need a zoning permit or “plot plan” review to ensure the coop meets mandatory setbacks — usually 5 to 20 feet from property lines and 20 to 35 feet from neighboring dwellings.

Sanitation standards apply broadly across all jurisdictions. Animal quarters must be designed to ensure safe, healthy, and sanitary conditions for animals on premises, and must be maintained to discourage the concentration and breeding of insects and rodents. These standards are not optional — failure to maintain them is the most common trigger for nuisance complaints and code enforcement actions against farm animal owners.

Waste management deserves particular attention in New Mexico’s arid climate. Manure must be stored and disposed of in a way that prevents runoff into drainage channels and does not create odor nuisances. Most county environmental health departments publish specific guidance on composting and disposal timelines. New Mexico’s high-desert sun also creates structural challenges: the climate and predators like coyotes and bobcats require shaded, well-ventilated, and predator-proof coops and enclosures.

For larger livestock like horses and cattle, adequate fencing is both a practical and legal requirement. New Mexico historically follows a “fence-out” approach to livestock management, meaning in unincorporated or open areas, counties do not have general authority to disallow the free running of livestock — but within municipalities and on residential properties, you are responsible for secure containment. An owner who willfully allows livestock to run at large is guilty of a misdemeanor under NMSA 1978. Proper fencing protects both your animals and your legal standing. If you are considering ruminant animals like goats, sheep, or cattle, understanding their containment needs is part of responsible ownership.

County and City Ordinances That May Override State Rules in New Mexico

One of the most important things to understand about keeping farm animals as pets in New Mexico is that local ordinances frequently impose restrictions that go well beyond — or in some cases directly conflict with — what state law might seem to allow. The state sets a floor; counties and municipalities can build walls much higher.

The range of local approaches is wide. In Gallup, backyard chicken hens are allowed under specific conditions, but all other poultry or fowl is prohibited — including ducks, quail, geese, turkeys, pigeons, and peacocks. A city like Albuquerque takes a more permissive stance for poultry but still prohibits most large livestock in standard residential zones. Rural counties like Catron, Harding, and De Baca have minimal restrictions and largely defer to state livestock law.

The Animal Protection of New Mexico maintains a directory of animal control ordinances for cities and counties including Alamogordo, Deming, Gallup, Rio Rancho, Santa Fe, and others — a useful starting point when researching your specific jurisdiction. Because ordinances change, always verify directly with your local planning and zoning office or animal control department.

HOA rules present a separate layer of private governance. Some HOAs have a formal variance or approval process that allows exceptions; others have absolute prohibitions with no appeal pathway. Unlike municipal ordinances, HOA restrictions are enforced through civil contract law rather than government authority, but the practical effect — losing your animals or facing fines — is the same. Check your deed restrictions and CC&Rs before you purchase any property with plans to keep farm animals.

Noise ordinances are another local tool that directly affects farm animal owners. While most urban areas like Santa Fe and Las Cruces strictly prohibit roosters in residential zones, Albuquerque is a notable exception, allowing one rooster per household. However, even where legal, roosters are subject to “Red Tag” noise ordinances — if a bird’s crowing is audible inside a neighbor’s home with windows closed, it can be declared a nuisance and removed. Similar noise-based nuisance standards apply to other vocal animals, including goats and pigs.

Important Note: Violating local animal control ordinances in New Mexico can result in civil fines, criminal misdemeanor charges, or both, depending on the severity and nature of the violation. Do not assume that because your neighbor keeps the same animals, your setup is automatically legal — ordinances are enforced on a complaint-driven basis, and your specific lot, zone, and structure placement all matter.

Right-to-Farm Laws and How They Apply to Pet Farm Animals in New Mexico

New Mexico’s Right to Farm Act is a meaningful legal protection for agricultural operations — but it does not apply equally to everyone keeping farm animals as pets. Understanding exactly what it covers, and what it does not, helps you set realistic expectations about the protection it offers.

The New Mexico Right to Farm Act was initially passed in 1981 and is codified as NMSA 1978, Sections 47-9-1 to -7. The purpose of the law is “to conserve, protect, encourage, develop, and improve agricultural land for the production of agricultural products and to reduce the loss to the state of its agricultural resources by limiting the circumstances under which agricultural operations may be deemed a nuisance.”

The core protection works like this: any agricultural operation is not, and shall not become, a nuisance by any changed condition in or about the locality of the operation if the operation was not a nuisance at the time it began and has been in existence for at least a year. What this means essentially is that once an ag operation has been in existence for a year, a neighboring landowner may not bring suit for nuisance complaining about the operation.

A 2016 amendment strengthened this protection further. The amended law provides that no cause of action based on nuisance may be brought by a person whose claim arose following the purchase, lease, rental, or occupancy of property proximate to a previously established agricultural operation or agricultural facility, except when such previously established operation has substantially changed in the nature and scope of its operations. This is particularly relevant in New Mexico’s rapidly growing communities, where new residential developments sometimes appear adjacent to long-established small farms.

However, the Right to Farm Act’s coverage for hobby-scale pet farm animals has limits. The Act protects “agricultural operations,” which includes breeding, hatching, raising, producing, feeding, keeping, and slaughtering farm animals for commercial purposes, as well as the production and keeping of honeybees and bee products. The phrase “for commercial purposes” matters. A purely personal, non-commercial arrangement — two pet goats, a backyard flock of hens — may not qualify as an “agricultural operation” under the Act’s definition, leaving you more exposed to nuisance complaints than a commercial farmer would be.

Under the 2025–2026 amendments, an agricultural operation in New Mexico cannot be declared a nuisance due to changed conditions in the locality — for example, a new housing development moving in next to an established coop. If your setup qualifies as an agricultural operation and has been in place for at least a year, this protection can be a meaningful shield against neighbor-driven complaints. For context on how New Mexico’s agricultural and wildlife laws interact, see our coverage of endangered animals in New Mexico and types of bats in New Mexico, both of which touch on the state’s broader regulatory framework for animals.

The Right to Farm Act also does not override zoning law. If your property is zoned for residential use and livestock are prohibited under that zone, the Act does not give you the right to keep them anyway. It protects qualifying operations from nuisance lawsuits — it does not supersede zoning ordinances, permit requirements, or county land-use codes. Always secure proper zoning approval and permits first; the Right to Farm Act is a defense, not a permission slip.

If you are weighing whether farm animals are the right fit for your household, it is worth exploring low-maintenance pet options or reviewing the animals that tend to be poor pets before committing to a species that carries significant legal and care obligations. For those who do move forward, the key takeaway is straightforward: research your zone, contact the NMLB for livestock registration requirements, pull your local ordinance, and check your HOA documents — in that order. New Mexico rewards prepared owners with genuine flexibility; it penalizes those who skip the paperwork.
